Application tiled September 7. 1&85. Serial No 176,405. (No model.)

To all whom, it may concern.-

Be it known that I, JOHN F. ALLEN, of Martinsdale, in the county ofMeagher, in the Territory of Montana, have invented certain new anduseful Improvements in Castrators, known as the Horsemans Favorite, analdo hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and usethesame, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

My invention has for its object to provide an improved and simplifiedconstruction of that class of veterinary surgical instruments known as"castrating-instruments, and the features of novelty consist,essentially, in the details of construction and general arrangement ofparts, all as will be hereinafter fully described, and specificallydesignated in the claim.

In the accompanying drawings,Figure 1 rep resents a side elevation of myimproved device, and Fig. 2 a detail view of the same.

Similar letters of reference indicate likeparts in both figures.

Referring to the drawings, A represents the lower orstationary member ofthe instrument, having an elongated handle at one end terminating ina'loop, a, for the reception of the fingers of the operator, andprovided at the opposite or front end with an upwardly-bent portion, b,having a vertical slot, 0, through the same, as fully shown in Fig. 2.

B represents the upper or movable member of the instrument, provided atits rear end with a handle and loop corresponding in size and shape tothat of thelower member, A, and pivoted at its front lower end within arecessed lug, d, upon the said lower member, as fully shown in thedrawings. To the front upper end of the movable member B is pivoted therear end of a hook, O, the front hooked' the hook is drawn in throughthe slotc, thereby drawing out the testicle-cord previous to completingthe operation of castration.

By means of myimprovements the surgical operation is greatly facilitatedand attended with less risk and trouble than by the use of the ordinaryappliances for the same purpose.

Having thus described my invention, what I claim as new and useful, anddesire to secure by Letters Patent, isv The herein-described veterinarysurgical instrument, consisting of the lower stationary member, A,provided with the elongated handle and loop at one end and with theslotted bent portion at the opposite end, and the upper mo able member,B, pivoted to thelower member, A, and provided with the hook U,substantially as and for the purpose specified.

In testimony that I claim the foregoing as my own I affix my signatureinpresence of two witnesses.
